Answer:

116 mg

Step-by-step explanation:

From the statement we have that a patient receives 1 1/3 mg of medicine per kilogram of his weight.

The first thing is to pass the mixed number 1 1/3 to a rational number, like this:

1 + 1/3 = 1.33

So it would be 1.33 mg of medicine per kg, if the patient weighs 87 kg, he should be given a total of:

1.33 * 87 = 116

A total of 116 mg should be given to that patient.

Solve 2x^3+7x^2-2x-1=o​
Mashcka [7]

Answer:

x=\sqrt{3}-2\\x=-\sqrt{3}-2\\x=\frac{1}{2}

Step-by-step explanation:

This is a hard one

We have to use the rational root theorem

2x^3+7x^2-2x-1 = 0

We have to find all the factors of a and d and put them in a fraction

a=2\\d=-1\\\frac{1}{1,2}

We then plug them into the equation to see if any of them work

The equation isn't true when plugging 1, but is true when plugging in 1/2

factored form of 1/2 is (2x-1)

Then we divide the original equation by (2x-1) (you can use synthetic division or long division, it would be hard to type out the process for that) to get x^2+4x+1

So now the equation is (2x-1)(x^2+4x+1)

Solve the second half of this equation using the quadratic formula to get

\sqrt{3}-2 and -\sqrt{3}-2

We already know the solution for the first half of the equation (1/2)

So the final answers are:

x=\sqrt{3}-2, -\sqrt{3}-2, \frac{1}{2}
